UNITED STATES PATENT OFFICE.

PAUL A. SABBATON, OF ALBANY, NEW YORK.

IM PROVEMENl IN SIFTING-SHOVELS.

Specification forming part of Letters Patent No. 22,514, dated January 4, 1859. A

Y part ot' this specification.

Figure l is a perspective view of the improvedshovel. v

The sifting or screening shovels now in use are either made wholly of sheetor bar iron or in part of both; and, as these materials are lexihle in their nature, they are liable to bend, and thus lose their form, and consequently the shovel, when constructed ot'these materials, no matter how well they may be put together, is liable to soon get out of order and become unserviceable, in addition to the other defects of being expensive to construct, and clumsy, unwieldy,l and fatiguing to handle.

The object ot' my invent-ion is to make the shovel light, strong, and durable by forming it of a material that shall combine these characteristics when the bars and its other parts are cast thin, and thereby enable the same to withstand the wear and tear that it is subjected toin shoveling and sifting coal and other broken material, and in assorting the different sizes of coal, coke, &e., and other purposes to which it may be applied, and at the same time render it light and convenient to handle. To effect these objects I do not in any manner alter the form of lthe shovel, and simply propose making the shovel in the usual or most approved form, as represented in the drawing, and of cast-iron'properly annealed and made malleable in the usualmethod, by which means it is made a light, durable, strong, and cheap shovel, and capable of varying the spaces bctween the bars, of separating and sifting .all

ordinary substances, such as coal, coke, pota toes, or other. articles, and materials ot' a like character.

The handle ot the shovel may be formed, adjusted, and afxed to the sifting portion in the most convenient methods or to suit the views ofthe constructer; but it is believed that the plan of handle represented in the drawing is best suited tothe design.

Having thus described my invention, I claim and desire to secure by Letters Patent- As an improved article of manufacture, a screening-shovel composed of malleable cast iron and otherwise made, as herein shown and described.
